lost connection at every 1st loading mean that you having an OOS error town which there's no solution for that yet, even Z not sure what the problem is it, it's cause of many thing such inventory, getting unreleased items etc, so there's no answer for your problem even after restore previous you can play but actually the data wasn't save.

HiGreat, you're right, I haven't seen it before because of errors, When erros fixed it can't do sell from because :1) the sentence is from ==> Inventory (I suppose it is from sell to inventory2) the link is : [You must be registered and logged in to see this link.] so no sales from inventoy.
